Case Type   : MOT
Case Name   : 结合MOT表，函数相关DDL
Create At   : 2020/10/10
Owner       : opentestcase001
Description :
    1.设置enable_incremental_checkpoint参数为off,并重启数据库
    2.创建MOT表，创建函数，清理数据
    3.恢复环境默认配置，修改enable_incremental_checkpoint为on，并重启数据库
Expect      :
    1.设置成功，重启数据库成功
    2.创建内存表成功，函数创建成功，清理环境成功
    3.修改参数成功，重启数据库成功
